sshfs 是基于fuse 开发的可以像使用本地系统一样，通过ssh 协议访问远端服务器文件，有好多方便的用途
- 数据同步
- 数据加密访问
- 做为共享数据卷（基于给容器使用）
安装

-o password_stdin read password from stdin (only for pam_mount!)
-o SSHOPT=VAL ssh options (see man ssh_config)
FUSE options:
-d -o debug enable debug output (implies -f)

-o use_ino let filesystem set inode numbers
-o readdir_ino try to fill in d_ino in readdir
-o direct_io use direct I/O
-o kernel_cache cache files in kernel
-o [no]auto_cache enable caching based on modification times (off)
-o umask=M set file permissions (octal)
-o uid=N set file owner
-o gid=N set file group

- 创建挂载点
mkdir -p /opt/ssh - 挂载远端服务器
sshfs root@remoteserver:/opt/ /opt/ssh/ 按照提示操作即可 - 查看挂载目录
说明
类似基于fuse 开发的文件系统还是比较多的，对于我们实际中的开发还是挺方便的
